Weighted-Average Anti-Dilution

Weighted-average anti-dilution adjusts an earlier investor's conversion price in a down round based on the size and price of the new issue, more mildly than a full ratchet.

This method recalculates the conversion price using a formula that weights the existing shares, the new (cheaper) shares and the amount raised, so the adjustment is proportionate rather than absolute. 'Broad-based' versions include options and convertibles in the share count, softening the impact further; 'narrow-based' versions are harsher.

Broad-based weighted-average anti-dilution is the market norm in Indian and global venture term sheets because it balances investor protection with fairness to founders, unlike the punitive full ratchet.
